T0 ALL WHOM IT MAY CONCERN:

Be t known that I, W. E. HARDIN, of Bowling Green, in the county ofPerry, and State of Missouri, have invented a new and useful Improvementin Ploughs; and I do hereby declare that the following is a full andclear description thereof. reference being had to the accompanyingdrawings and to the letters of reference marked thereon.

l This invention relates to the employment of a wheel or roller underthe heel of the plough, the exterior face of the said wheel or rollerbeing arranged to coincide with the vertical plane in which theland-side of' the plough is located, the metal plate Which'forms theland-side in the old construction of' ploughs being omitted in this, togive room for the wheel.

The object of thc invention is to lessen the draught of the plough, byproducing rolling friction insteacl'of sliding, as is the case where theland-side is-formed of a straight plate of metal.

To enable those skilled in the art to make and use my improvedplough, Iwill proceed to describe its construction and operation. I

Figure 1, of the drawings, is a side elevation of the improved plough,and

Figure 2 is a rear end elevation of it.

The plough A B may be of any approved form o1' pattern, with theexception of the land-side, which is omitted in the present instance, soas to allow room for the wheel or roller C, the said wheel or roller inreality forming the land-side of the plough. This wheel C is attached toa shaft, C', which has its bearings in the lower end of the handlepieceor post a, and in the piece a attached to the mouldboard, as is clearlyshown in i fig. 2: -The bearing at a may be formed by means of ascrew-pivot point, so as to allow a. ready means of ""*Mw adjustment ofthe parts.v The exterior face of the wheel C may be formed either withor without a flange, c,

on the periphery, and the said face of the wheel may be either flat orconvex.

The object of the wheel C, employed as above described, is to reduce thefriction to a minimum, byproducing rolling instead of sliding friction.Ploughs constructed in this manner are more easily handled in turningthan those with straight land-sides.

Having described my invention, what I claiml is- The wheel C, whencombined with a plough, B, in the manner and for the purpose set forth.
